A new “Email Magic Link” button is added to the standard WordPress and WooCommerce login screens. If there is a user 
account for the username filled out, they will receive an email with a link to log them in without a password.
All emails sent from WordPress will contain login codes in links pointing back to the website:
<ul>
<li>Comment reply emails</li>
<li>Abandoned cart emails</li>
<li>Membership reminder emails</li>
<li>etc.</li>
</ul>
No configuration is required, by default:
<ul>
<li>Autologin URLs work for one week</li>
<li>Emails to administrators are excluded</li>
<li>Emails on exclusion shortlist are not modified</li>
</ul>
An API is available for developers to use autologin codes elsewhere in WordPress, e.g. push notifications, and to conditionally disable the plugin’s use. Code is published on GitHub, uses WordPress Plugin Boilerplate, conforms (mostly) to WordPress Coding Standards, and is unit & integration tested.

Assign multiple bylines to posts, pages, and custom post types via a search-as-you-type input box. Co-authored posts appear on a co-author’s archive page and in their feed. Co-authors may edit the posts they are associated with, and co-authors who are contributors may only edit posts if they have not been published (as is core behavior).
Add writers as bylines without creating WordPress user accounts. Simply <a href="https://github.com/Automattic/Co-Authors-Plus/wiki/Creating-and-editing-guest-authors" rel="nofollow ugc">create a guest author profile</a> for the writer and assign the byline as you normally would.
On the frontend, use the <a href="https://github.com/Automattic/Co-Authors-Plus/wiki/Template-tags" rel="nofollow ugc">Co-Authors Plus template tags</a> or the <a href="https://github.com/Automattic/Co-Authors-Plus/wiki/Blocks" rel="nofollow ugc">block editor blocks</a> to list co-authors anywhere you’d normally list the author.

Co-Authors Plus is an almost complete rewrite of the <a href="https://wordpress.org/plugins/co-authors/" rel="ugc">Co-Authors</a> plugin originally developed by Weston Ruter (2007). The original plugin was inspired by the ‘<a href="https://txfx.net/2005/08/16/new-plugin-multiple-authors/" rel="nofollow ugc">Multiple Authors</a>‘ plugin by Mark Jaquith (2005).

Co-Authors Plus

No support at all , also it doesn't work with wpml

No Support - Not compatible with WPML

Not working

Works!

I rarely ever give 1 star reviews, but developers who take over a plugin - making a breaking change that took a while to resolve - and then refuse to follow standard practice by providing a changelog (despite requests) for future updates, cannot be trusted.

Avoid at all costs.

Cannot trust developers
